Description

Technical Field

[0001] This invention belongs to the field of exhaust gas treatment technology, and in particular relates to a heat insulation device for a cylinder based on exhaust gas treatment. Background Technology

[0002] For components such as catalytic converters and mufflers in exhaust gas treatment systems, heat insulation devices are required to provide heat insulation and blocking. Existing heat insulation devices are mainly divided into two types: one is a sleeve-type heat insulation cover that is fitted over the outer surface of the component to provide overall heat insulation and blocking; the other is an arc-shaped heat insulation cover type, with the inner wall fitting against the outer wall of the component and the outer wall fixed to the frame to achieve localized heat insulation in order to prevent heat from being conducted to the vehicle frame or to provide heat insulation and blocking for other surrounding components.

[0003] Existing insulation devices are relatively simple and still suffer from poor insulation performance. In addition, most insulation devices are fastened with screws or bolts, which, due to space limitations, makes installation and removal difficult, hindering the operation of workers and the maintenance and repair of the insulation device and the cylinder structure. Summary of the Invention

[0004] The purpose of this invention is to provide a heat insulation device for a cylinder body based on exhaust gas treatment. By designing a novel heat insulation device, the cylinder body structure can be completely wrapped by an intermediate cover, a first end cover, and a second end cover. At the same time, the design of an external arc-shaped heat insulation cover can further reduce heat radiation and further improve the heat insulation effect, thereby improving the heat insulation effect of the heat insulation device.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
